Basement rocks to the Athabasca Basin, Saskatchewan and Alberta
Bibliographic record
Abstract
The basement to the Athabasca Basin comprises rocks of the Rae and Hearne provinces and the Taltson magmatic zone. The Rae Province is characterized by mainly metasedimentary supracrustal sequences, including the Murmac Bay Group, and Archean and Proterozoic granitoid rocks. The Hearne Province contains Archean granitoid gneiss with interleaved supracrustal belts including the Archean Ennadai Group, the Paleoproterozoic Hurwitz Group, and other rocks of unknown age. The eastern Hearne Province is dominated by Wollaston Supergroup metasedimentary rocks. The Taltson magmatic zone contains a basement complex that was intruded by ca. 1.99 - 1.96 Ga continental magmatic arc granitoid rocks and 1.95 - 1.92 Ga peraluminous granitoid rocks. Numerous structural features affected the Athabasca Group and its basement rocks. Their histories were generally protracted and included multiple displacements under ductile and brittle conditions. Mackenzie diabase dykes cut the Athabasca Group, providing its minimum age. The Carswell Structure is thought to be the result of an Ordovician meteorite impact.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
